| Abstract | This paper presents a robust methodology toward reliable supervised urban classification cooperatively handling spectral content from multispectral image and high resolution spatial information from QuickBird images. The main contribution is to provide a new schema for image fusion of morphological/spectral features using a soft margin SVM classifier. This investigation reproduces the spectral characteristics of original multispectral image and preserves, faithfully, the spatial information of the high resolution image. The accuracy and the effectiveness of the proposed approach were evaluated and compared with those of Maximum Likelihood (ML) and ECHO (Extraction and Classification of Homogeneous Objects) algorithms. The experiment results, conducted on urban area in Riyadh Saudi Arabia, show that the maintenance of spectral characteristics in fused images is the best, and the structure is smoothly integrated into the morphological features even for small/overlapping objects in images. This is revealed by improving the classification accuracy reaching 92%. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
